It is incumbent on the propounder of a Will once the Will is being challenged to establish its regularity. But once the court is satisfied prima facie of the regularity of the will, the burden of proof shifts to the party challenging the will. See: Eyo v. Inyang (2001) 8 NWLR (pt 715) 304, Okelola v. Boyle (1998) 2 NWLR (pt 539) 533; Amu v. Amu (2007) 7 NWLR (pt 663) L64, Adebayo v. Adebojo (1973) Alf N.L.R.297 and Johnson & Anor. V. Maja & Ors. 13 WACA 290.
